according to this post it would appear that news is already leaking out regards to the company’s efforts to use bimatoprost for scalp hair and it sounds like bimatoprost is having the desired effect on scalp hair. We don’t know yet if that desired effect is strong enough to an improvement over minoxidil but at least we do know that bimatoprost does have a positive effect on scalp hair growth.
